I've been a GM guy my whole life but just bought a 2002 Lightning. Who says you can't change? This is my daily driver so I don't want to go overboard (yet). My questions are if someone knows what HP and TQ differences in the K & N replacement filter and the FIPK system or any other air filter system. Is the FIPK worth the difference? Is the fuel economy any different? Also, I have a major traction issue with this truck. It has F1's and they are in good shape. 1st gear is almost useless (in and out of the gas to try to get it to hook up). I've had strong muscle cars in the past but don't know a lot about this truck other than I like it alot. What mods to start with? Any info on air filter systems, chips, traction devices or anything I left out would be appreciated.
